This is the final update from your tweets, emails, comments and Facebook messages. Here is the review that you've written for the iPhone 4. (For the most part, you seem to like it...aside from that pesky antenna issue.)

The Early Impressions

The Design

This is definitely the sturdiest phone i've ever felt and the first impression after being held is "wow." It feels less like a cheap toy and more like an old metal camera.
- Gabriel Militello

It feels like it's the Lamborghini of phones. (I want to always use it but I am scared to handle it.)...The feel of the volume buttons are precise and tactile, does not feel dull like the 3g. The toggle switch also has a very short throw in between silence and sound.
- DJ Peterson

Performance

[Ed note: Side by side vs 3GS...gets good toward the middle]
- DJ Peterson

The speed is incredible and is blazing fast. It feels more akin to the iPad than anything else. I've used a 3GS a bit and it definitely is quicker. Not enough to say "WOW" but it's enough to know that his baby has more juice. One thing to note is safari feels a lot zippier than the GS and I attribute this to the large amount of ram

I can honestly say the new iPhone was a great investment!! Everything is running sooo much better!!

The Reception/Call Quality

The iPhone 4's apparent reception seems to decrease when you hold the phone in your hands (around the antennas)... We've tried placing fingers in different positions to see if there is an exact spot triggering it, but all we seem to find is that, with great consistency, the bars plummet when we hold it and the palm and fingers come in contact with the sides.

This is exactly what I'm getting. It's a great phone when left on the table, but the moment you pick it up, it's a paperweight. I've had more dropped and failed calls today with the 4 than I ever had with the previous iPhones combined. Seriously.
- magpie maniac

I have the same exact problem. The signal is all over...call quality has dropped and I am unable to talk clearly while holding the phone....even without touching the black lines on the sides.

Just had a crazy clear convo from home where drop calls happen a lot...[then later] place where my iPhone always (I mean always) dropped? Didn't drop with iPhone4.
- GilCabrera

If my phone is lying on my desk/couch/etc.., I have decent service in my house but when I pick the phone up with a full hand (palm + all fingers) my service drops quickly to "No Service". If I use two or three fingers & hold it near the top, I have at least 2 bars & I can use the phone to make calls...
- Slim Johnson

Mixed bag here. I seem to get more bars in areas of my house where I didn't use to. On the other hand, I also seem to get less bars in other areas. Needs further testing for me to make a solid judgment.
- Gabriel Militello

I tested my old phone against my wife's new one and the quality of the call sounded better on the iPhone 4...reception is improved.

Some background, I have a DLink dual band wireless N router in my house, the new iPhone 4 is supposed to have wifi-N in it, as compared to the old 3G which only had wifi-G, so i was expecting to see a speed bump when I ran speedtest on the new iPhone 4. As you can see in the attached screenshots, the 3G wifi speed is actually faster than the the results for the new iPhone 4 which I did today (the results were pretty consistent after multiple tests today)...But during the 3G test...[the iPhone 4 is, somehow, much faster]

The Battery

I've been using the shit out of it for about 3 hours...At 80%...Went all day without killing any [apps]... Just checked and have 9 running.

I am bit biased here because I am coming from a 3g which had a mediocre battery life at best. With that out of the way, the iPhone 4 has an amazing battery so far and I've been using it profusely since 11am and its now 4pm with a battery sitting at 83% from a 99% charge. I'll need more testing but this thing seems rock solid in the battery department.
- Gabriel Militello

Just like when I got my iPad and ran it through some 'heavy' use, the new iPhone is no different. I've gone all day without charging it (outside of the initial activation) and I'm nowhere near the halfway point. I didn't even plug it into the car adapter on the way home; I actually listened to the radio! I had wifi running with numerous apps in the background. Taking photos and video. Surfing the web. A FaceTime call. Still going strong!
- Sergio Azevedo

I just finished playing Need for Speed shift for 30 minutes and the battery is only at 84%....nice!...since my 3g battery would have taken a 30-35% chunk of battery.

Battery length seems great. I used it all last night surfing [over Wi-Fi] Gizmodo, Modmyi, App store, playing with settings, downloading music, and with not even a 100% full charge it still wasn't at half way when I went to bed 3 hrs later.

FaceTime

- aglanon

It is really awesome. Considering I'm traveling more, this is really going to be cool so I can see my wife and daughter instead of just hearing. I won't fall into the 'it changes everything' gimmick, because I don't think having it only on WiFi is a huge change. In any event, it is really cool.

A co-worker of mine had a back injury and went to the chiropractor. While there he was asked about his work setting (chair, desk height, etc.) and he FaceTimed me. I gave the tour of his desk, and she suggested several things right on the video to help his back. It was great!

The Foibles

The temperature of this phone is noticeable warmer. It doesn't get hot, but it is warm. I wouldn't say it's uncomfortable. However, after a day or so of heavy use I suppose the real verdict will come in on it.
- Cody

I discovered a small ding on the top end of the phone between the glass and the metal bezel. The picture doesn't do it justice, but that's the best I could do with my MacBook camera. It's frustrating because I like to keep my stuff immaculate and I am always thinking about resale value...

Bluetooth
I got my iphone 4 today and connected it with my Bluetooth Parrot RKi8400 car stereo. What I found was is that when playing music via Bluetooth it kept cutting out. Where as my 3G never had this problem. I would think with a faster processor this wouldn't be happening, but maybe with the new accessibilty features something got messed up. Who knows! It just sucks.
- Cory Johnson

Bad Vibrations
So I recieved my iPhone 4 today in the mail. Everything was going great for an hour or so. Then all of a sudden the screen shuts off and it started vibrating continuously at max vibrate. I was waiting for a reply to a text when it happend, and hadn't done anything out of the ordinary to cause it. I've tried to power it off, to reset it I've held all the buttons and every combination of them.

There's a problem with the iPhone 4's Retina displays: Some screens have a yellow tint…
Read more Read more

Just unboxed my new phone and synchronized with iTunes and decided to play a movie to see the new "RETINA DISPLAY" in action... There is a damn yellow line at the bottom of the screen about a 1/4 inch above the home button! Man am I pissed!!!! Even when I flip it around it stays at the bottom!
[Ed note: There are many reports coming in of yellow screens...NOT AGAIN!]

I just got my iPhone 4 today (ordered it from the Apple online store) and it has a yellowish discoloration of the LCD screen in the bottom left corner. I've been assigned a case number and was told for the fastest resolution to contact the local Apple retail store. They stated they would need until Friday to determine if they'll have an "extra" to hold for a defective product swap. They said I may have to wait a week until their stock is at a point where they can place one to the side for me. I told them I'd rather wait until I wouldn't have to fight the chaos of launch week anyways...

Spotted Screens (several cases reported)

I have about 9 white dots of varying but constant brightness in the top left corner of my screen. See attached photos.

I just got my IPhone 4 maybe an hour ago and was checking around for the yellow spot problem. Well, I didn't have the problem that I know of but something else. There are two bright spots and one really tiny faint spot that is very bright. It's almost like a dead pixel but i think it's some sort of backlight issue?

AND THERE'S A BOUNTY!

Those who give us the absolute best shots, most critical observations and deep comparisons will be rewarded not just with fame and glory, but with $20 iTunes gift cards. We won't be too stingy with 'em, promise, just send us great, usable stuff that we don't already have!

The End: Thanks for everyone's participation in our grand experiment! I find it fascinating that, while major reviewers failed to uncover many of the iPhone 4's issues (like the antenna), the power of the masses spotted them with no delay. Awesome.
